of elements (1, 2) which are respectively fastened to a rotating leaf (5) and to a
fixed wall (4), a first element (1) being integrally fastened to the leaf (5) and
a second element (2) being rotatably fastened to the wall (4). The abovementioned
elements (1, 2) are provided with means (3) for rigidly fastening them together, acting
in the horizontal direction and consisting of a snap-engaging mechanism in which elastically
deformable lugs (3a) integral with the second element (2) engage in a seat (3b) with
